WARNING
Pressurized hydraulic fluid can penetrate the skin and cause severe injuries.
Hydraulic fluid is under extreme pressure. Rest the bucket or attachment on the ground. Shut the
engine off, turn the key on, and move the hydraulic control lever through all movements several times
to relieve residual pressure in the system.
Failure to comply could result in death or serious injury.

Replace the hydraulic oil filter every 2000 hours or more frequently when operating conditions are severe.
Prior operation:
Keep all non-authorized personnel clear of the area. Park the machine on level ground in neutral with the parking
brake applied and the attachment lowered to the ground.
1. Release pressure in the hydraulic system. Install the
transport/service link into the locked position.
2. Slowly loosen the filler cap on the hydraulic reservoir to
release any residual pressure in the reservoir. Leave
the filler cap loose during the procedure.
3. Turn the filter counterclockwise to remove. Lubricate
the gasket and threads of the new filter with clean hy-
draulic fluid and install. After the filter makes contact
with the filter head tighten 1/2 to 3/4 turns.
4. Tighten the cap on the hydraulic reservoir.
